I just realized, even though Ingong came back as MC, the twin heroines, Hong sisters, never materialized even though they are his childhood friends. I guess even Cupid King can't do anything with them.
There's no way she'd fall for this fake ass MC and she already hated him by default in the og story too.
Na Ri was a sub-heroine, it's possible because of her status, Ingong never truly got along with her as he only got involved with Da Hee. That is the whole reason why Kang Lim approached her, he remember there was never any romance between them. Heck, that is why he got caught off-guard by Na Ri liking him because that didn't happened in ESW.
